7.0 ETHERNET COMMUNICATIONS
Ethernet/IP communications connections are provided through an RJ-45 connector(J8) in the lower right
corner of the main board. This port can be connected directly to a network port of a PC using a CAT 5e crossover
cable or to an IP router, hub, or switch using a standard CAT 5e cable.
Two LEDs are provided directly above the connector. The LINK LED is yellow and when lit, indicates ethernet
connectivity. The ACT led is green and when lit, indicates communication activity.
Communication protocol for the Ethernet/IP port is selectable using the position 2 switch of S2. If position 2 is
ON, EZ7 is selected. If position 2 is OFF, Modbus TCP/IP is selected.
IDR 2500s can be tied into a local Ethernet network (Intranet) or used on the Internet with a public IP Address.
Each device that is connected directly to the ethernet network requires a unique IP address. The IP address is
entered through the pushbuttons located on the display board. Section 5.0 describes the use of those buttons.
